DOOR-JAM B.

SPECIFICATION forming part of Letters Patent N o. 484,551, dated October 18, 1892.

v Application filed March 26, 1892. Serial No. 426,538. (No model.)

To all whom it may concern:

Be it known that I, MATEIAS CLAssEN, a citizen of the United States, residing at Kalamazoo, in the county of Madison and State of Nebraska, have invented a new and useful Door-J amb, of which the following is a specification.

rlhe invention relates to improvements in jambs for doors.

The object of the present invention is to provide an adjustable cushion-j amb for doors, adapted to fit closely to a door to exclude the air and to prevent a door binding by reason of swelling of the parts or the like.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure lis ahorizontal sectional View of a portion of a door provided with a jamb embodying the invention. Fig. 2 is a vertical sectional view.

Like numerals of reference indicate like parts in both the figures of the drawings.

lv designates a jamb-strip, which has its inner edge 2 oppositely beveled and which is secured to a door-frame by hinges 3, arranged at the inner edge 2 and permitting the jamb` strip to move inward or outward to adjust itself to a door. The jamb-strip is held in contact with the adjacent edge of a door, when the latter is closed, by spiral springs 4, inter posed between the strip and tne adjacent portion of the door-frame, whereby the jambstrip is cushioned. The inner edge of the jamb-strip is covered and the hinges are concealed and protected by an abutting strip 5, which is secured to the door-frame and projects over the inner edge of the j amb-strip. The frame-strip t has lits edge 7 beveled to protect the jamb-strip from injury in case the door should swell, sag, or the like. The j ambstri'p and the door are protected by plates 8 and 9,secured, respectively, to the jamb-strip and the door and projecting slightly from those parts and adapted to bear against each other when the doorl is closed. The plates are arranged at intervals on the door, as shown, and the inner edge l0 of the plate 9 and the outer edge 1l of the plate 8 are beveled and are adapted to facilitate the closing of the door. The projecting faces of the plates bear against each other and prevent the edge of the door coming in contact with the strip, and thereby avoid injury to either the door or the strip.

Vhat I claim is- 1. The combination, with a frame, of a jamb-strip having its inner edge attached to the frame by hinges, springs interposed between the jamb-strip and the frame, and an abutting strip secured to the frame and projecting over the inner edge of the jamb-strip and serving to conceal and protect the hinges and the inner end of the jamb-strip, substantially as described.

2. The combination, with a frame, of an elastic jamb-strip hinged to the frame, a plate secured to the outer face of the jamb-strip and projecting slightly from it and having its outer end beveled, and a plate designed to be secured to a door and having its inner end beveled, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
